Abstract
The flow rate control device comprises a basal plate block wherein a single input port into which a fluid flows, a single output port from which the fluid flows out, two inflow channels whose proximal ends are connected to the input port and two outflow channels whose terminal ends are connected to the output port are formed, and two flow rate control units arranged on the basal plate block, and one of the flow rate control units is arranged between one of the inflow channels and one of the outflow channels, the other flow rate control unit is arranged between the other inflow channel and the other outflow channel, and each of the flow rate control units is configured to be capable of operating independently.
